Which statement about the E7024 designation is correct?

Which statement about the E7024 designation is correct?

• A. The digit 2 indicates Flat/Horizontal Position
• B. The digit 2 indicates 2 inches diameter
• C. The E stands for Energy
• D. The 7 indicates seven passes

Answer: (A)

In the AWS welding electrode designation, the first letter E means electrode. The two digits that follow express the minimum tensile strength of the weld metal, in ksi. For this code, that strength is 70 ksi. The last two digits describe the coating type and the welding positions the electrode is suited for. In this case, the digit 2 indicates the electrode is intended for flat and horizontal welding positions, not for vertical or overhead. The other statements aren’t correct because the designation does not specify diameter, energy, or number of passes; the digits are about strength and positional suitability.
